Chemical Bonding Result Question 27
27. Arrange the following as stated.
“Increasing strength of hydrogen bonding $(X-H-X)$.”
$\mathrm{O}, \mathrm{S}, \mathrm{F}, \mathrm{Cl}, \mathrm{N}$
$(1991,1 M)$
Show Answer
Solution:
- Strength of hydrogen bonding in $X-\mathrm{H}-X$ depends on electronegativity as well as size of $X . X$ with higher electronegativity and smaller size forms stronger $\mathrm{H}$ -bond. Hence, increasing order of strength of $\mathrm{H}$ -bond is
$\mathrm{S}<\mathrm{Cl}<\mathrm{N}<\mathrm{O}<\mathrm{F}$
